How to work it out

  1. Divide the part by the whole: 90 ÷ 300 = 0.3
  2. Multiply by 100: 0.3 × 100 = 30%
  3. Check: Work backwards: 30% of 300 is 0.3 × 300 = 90.

Another method. As a proportion of part to whole: 90/300 = p/100, so p = 90 × 100 ÷ 300 = 30%. Both methods always give the same answer.

In a spreadsheet: =90/300*100. Dividing the wrong way round (whole ÷ part) gives a different answer. The number after “of” is always the whole, so it goes on the bottom.

What the result means

90 is between a quarter and a half of 300. The part that is left, 210, is the other 70%.

Test scores: 90 correct answers out of 300 is a score of 30%, which on a common US grading scale is an F.

Turning it around

If you know that 90 is 30% of a number, you can get that number back: 90 ÷ 0.3 = 300. And 300 as a percentage of 90 is 333.3333%, a different answer, because the whole has changed.
